A Taxonomic Study On The Subfamilies Brachistinae And Helconinae (Hymenoptera:Braconidae) From China

The subfamilies Brachistinae and Helconinae are moderately large groups of Braconidae including393described species of11genera and232described species of33genera, respectively. The majority of Helconinae and Brachistinae are endoparasitoids of larvae of Coleoptera and Lepidoptera while a few species parasitize species of Diptera and Hymenoptera. Many species of the subfamilies are very important in natural control of agricultural and forest pests. The species of these two subfamilies from China are revised in the present work. This dissertation comprises two parts, general part and taxonomic part.The general part is mainly about taxonomic history of the subfamilies Brachistinae and Helconinae. In the taxonomic part,49species of six subgenera and five genera in two tribes of Brachistinae from China are recognized, of which one subgenus and41species are new to science, and two genera, two subgenera and five species are recorded from China for the first time;27previously known species of three genera from China with no specimens available for this study are also noted.54species of12genera in three tribes of Helconinae from China are recognized, of which one genus and48species are new to science, two genera and five species are recorded from China for the first time;29previously known species of nine genera from China with no specimens available for this study are also noted. Information of diagonostic characters, distribution and hosts are provided for each tribe, genus, subgenus and species. Keys to tribes, genera, subgenera and species are also provided.Types are all deposited in the Parasitic Hymenoptera Collection of Zhejiang University (ZJUH), Institute of Zoology, Chinese Academy of Science (IZAS), Shanghai Entomological Museum of Chinese Academy of Sciences (SEMS).
